To all whom it may concern Be it known that I, l v anrnn TnInM, a subject of the King of Prussia, and residing at Halle-ointhe-Saale, German Empire, have invented certain new and useful improvements in Apparatus for the'lProduction of Air-Gas, of which the following is a specification.

This invention relates to oil feeding devices particularly as applied for the manufacture of air-gas, for illuminating and heating purposes, from the lighter hydrocarbons, the air and the hydrocarbon being introduced into the carbureting-chaniber in definite proportions.

To prevent the direct passage of the hydrocarbon vapor from the vessel contain ing the hydrocarbon into the carbureting chamber, it has been the practice to employ a so-called siphon seal. This prevents the volume of already manufactured gas in the carbrusting-chamber from being enriched to excess on stoppage of the plant, or on a considerable change of temperature occuring. The employment of such a siphon (for instance in the form of a U-shaped pipe), has, however, the drawback that the sealing-liquid '(readily evaporated fuel) contained in the siphon is also exposed to evaporation. Thus the seal is destroyed as soon as this liquid has been evaporated, for instance through the plant remaining out of use for a considerable interval. To overcome this defect, I provide between the hydrocarbon reservoir and the carburetingchamber a vessel containing a sealing-liquid which is non-evaporable, or only slightly evaporable, whereby a permanent vaportight closure between the hydrocarbon reservoir and the carbureting-chamber is insured.

A preferred embodiment of my invention is illustrated in the accompanying drawing, in which Figure l'is a front elevation of the apparatus, certain parts being shown in sec tion. Fig. 2 is a longitudinal section through the apparatus Fig. 5 shows in sec tion, on a larger scale, the sealing vessel employed between the hydrocarbon reservoir and the carbureting chamher. and Fig. 4 shows in perspective view the structure by which the scoop is operated.

The apparatus consists of a tanlr a, in

nor a rotary blower E), which acts as a pump to suck air into and through the carburetor, and resembles the drum of a gas-meter. The blowe b is revolved by means of toothed gears 0', (Z, the latter one of which is driven by means of a rope-drum e. The gas-holder g is supported by the hood 7. which covers the blower Z). @n the blower being set in motion, it draws in air, which enters at the inlet 27 and passes through the sinuous, flat, sheet-metal duct it, which constitutes the carbureting-chamber. .iiimulta neously herewith the bucket 7c of an oscillatory scoop-device lifts a measured quan tity of hydrocarbon from the reservoir Z and empties it into a funnel m, located in a vessel 0, whose spout 1 leads to the duct It. The vessel 0 contains a sealingdiquid p, into which the tube n of the funnel m (lips whereby an edective vapor-tight seal is formed.

At the top of the casing 7 of the gas holder, there is fulcrumed a pivotal lever 14 the free end of which rests upon the hell 7 of the gas holder in such a manner that as soon as the bell g is full the lever 14. actuates the lever system 1.5 and 1.5 the bar 15 of which is pivoted at 15 and carries a brake shoe 10 forcing, the latter against the brake disk 17 arresting the disk and hence also a driving gear a d. When the hell {7 does not fill owing to the consumption of gas the brake is raised automatically and the apparatus thus supplies more gas.

The scoop device which receives its movement from a rod 18 and eccentric l8 rotated by the gear Wheels 0 and d, is also controlled by the lever system 15 and 15*. The rod 18 is connected with the arm 30 on the crank shaft 31; and by means of a link 32 the crank shaft is ctuinected with the scoop-device it. The. generated gas flows through the pipe 11 into the space below the hood 7" and thence through the hell 9 of the outlet 12 leads the gas to the place of consumption.

Mercury, glycerin or any other suitable slowly evaporable liquid may be used as sealing-fluid: and the mechanical details of the sealing-device may naturally be other than those. illustrated by Way of example in the drawing.

I claim:

An oil feeding device comprising an oil tank, a nip, a sealing vessel, and oscillatory means for intermittently operating liquid reaching above the lower orifice of 10 said scoop for transferring a quantity of said pipe in said vessel.

, oil from said tank into said sealing vessel; In testimony whereof I affix my signature said sealing vessel having an outlet spout in presence of two witnesses.

; approximately midway between top and .WALTER THIENL bottom of the vessel, a funnel closing the top of said sealing vessel for receiving the W'itnesses:

' oil from said scoop, a pipe extending below RUDOLPH FRIOKE,

said spout from said funnel, and a sealing F ERO GROSS.
